Is it possible to scan and capture the PCM and or TCM just using the EFI FlashScan V2?

I haven't found anything in the PDF's that clearly state how it's done. It appears a PC needs to be connected. I really wish there some documentation that is centered around the FlashScan V2 itself and how to use it.

Thanks for the read.
